Hay Creek Stream Diversion

Hay Creek Stream Diversion

Scope

Michels developed a diversion plan for Hay Creek to allow a pipeline crew to perform an anomaly dig to repair an imperfection of a high-pressure pipeline that crossed the creek. A 24-inch 250hp electric submersible pump and a 6-inch 27hp electric submersible pump were determined to be adequate to handle the creek's flow of 21,300 gallons per minute, to fit into the site's small footprint, and reduce the risks of the losing prime or encountering mechanical failure compared to other pump options.

Projects

Michels designed, furnished and installed a siphon system to draw down water elevation in a pond impoundment area and maintain upstream river flow during the removal of a high-risk dam. The system consisted of 14 30-inch HDPE siphons, flow-monitoring meters, stainless steel knife gate valves and a priming system.

Boardman Dam removal

Michels Dewatering group was tasked to design, install and operate a system to divert peak flows of up to 168,000 gallons per minute, or 242 million gallons per day, so that a pipeline could be open cut in dry conditions across the Conotton Creek.
